All of the following are evidence for the big bang except: A. Cosmic background radiation B. Almost all galaxies are red-shifted C. The sound from the bang echoes though the universe D. The universe is expanding
Answer: C. The sound from the bang echoes though the universe
Explanation:
Cosmic background radiation proves the big bang because it shows that as a result of the big bang, the early universe was really hot but cooled as it expanded. Cosmic background radiation is the result of that earlier heat.
Galaxies being red-shifted means that the space between galaxies is increasing which means that the universe is expanding which provides evidence for a big bang because particles move away the single point they are concentrated in.
There was no actual bang from the big bang and sound cannot echo through space so c is incorrect.

To control the population of insects, if insecticides are used then how it will affect the population of birds?
Answer: Birds are exposed to insecticides through ingestion by mistaking, they ingest pesticide residues when they trim their feathers with their beaks or may drink or bathe in contaminated water. The effects can range from death due to poisoning to a variety of effects such as weakening of eggshells, deformation and slow growth of chicks, lack of appetite, weight loss, immune system damage, hormonal disruption. In addition, insect-eating birds are at a loss when insecticides cause a drop in the number of insects available, especially when they have chicks to feed.
Explanation:
Insects are a class of invertebrate animals characterized by having one pair of antennae, three pairs of legs and two pairs of wings (which, however, may be reduced or missing). They comprise the most diverse group of animals on Earth with an estimated thirty million undescribed species, potentially representing more than 90% of the life forms on the planet. Moreover, they can be found in almost every environment on the planet, so they are not only highly diverse, but also incredibly abundant.
Like any species on the planet, insects play a vital role in the ecosystem, so that a change in the population can compromise the survival of everything around them. On the other hand, insects called "pests" are those insects observed in systems and whose populations cause damage to crops. Although both beneficial insects and pest insects are part of any ecosystem and are also present in human-managed systems. Humans combat these pests using insecticides, which are chemical compounds used to kill insects. They are usually very specific since the product only affects the organism it damages, leaving the rest of living beings and the environment unharmed. And they have low toxicity to humans and animals.
The most common way in which birds are exposed to insecticides is through ingestion by mistaking, for example, a pesticide granule for a seed, or indirectly, by consuming contaminated prey (insects). Birds may also ingest pesticide residues when they trim their feathers with their beaks or may drink or bathe in contaminated water. It should be noted that it also depends on the toxicity of the chemicals, the magnitude and duration of exposure. The effects can range from death due to poisoning to a variety of effects such as weakening of eggshells, deformation and slow growth of chicks, lack of appetite, weight loss, immune system damage, hormonal disruption. In addition, insect-eating birds are at a loss when insecticides cause a drop in the number of insects available, especially when they have chicks to feed.

What might happen to the genes that break down carbohydrates when cats eat lipids and fats, but no carbohydrates?
Answer:
Goes into resting position.
Explanation:
The genes become dormant or in resting position that break down carbohydrates when cats eat lipids and fats, but no carbohydrates because of no use of that genes. The genes can't give instructions to the hormones that produces enzymes which take part in the digestion of carbohydrates so due to no need for the genes of carbohydrates, the genes goes into resting position until carbohydrate is eaten by the cat.

John is testing the effect of temperature on the solubility of sugar in water.
He plans to determine the mass of sugar dissolved in a saturated solution.
He will begin with a known mass of sugar and add sugar to water until the
solution is saturated. He will then calculate how much sugar dissolved by
subtracting the remaining mass from the initial mass.
He organized data about his experiment in the following table:
Group A
Group B
Group C
Volume of water
100 mL
Temperature
25°C
1000 g
Initial mass of
sugar
800 g
Final mass of
sugar
Which factor should be the same in all three groups?
Answer:
As John is testing the effect of temperature on the solubility of sugar in water. To test this, he will measure the amount of sugar dissolved at different temperature level.Explanation:
I hope it's helpful for you ☺️The volume of water should be the same in all three groups.
What is solubility?Solubility is the property of a substance to dissolve in a solvent to form a homogeneous solution at a particular temperature and pressure.The volume of water should be the same in all three groups. This is because the experiment is testing the effect of temperature on the solubility of sugar in water, and any variation in the volume of water could affect the results.
By keeping the volume of water constant, John can ensure that any changes in the amount of sugar dissolved are solely due to changes in temperature and not changes in the amount of water. Therefore, he can compare the results of each group and draw conclusions about the effect of temperature on the solubility of sugar.

If Darwin knew of Mendel’s work, how might it have influenced his theory of evolution? Do you think this would have affected how well Darwin’s work was accepted?
Answer:
See explanation
Explanation:
Darwin proposed his theory of evolution on the premise of natural selection. According to him, organisms which possess favourable characteristics which enable them to survive in their environment are more likely to survive and reproduce, passing on these favourable characteristics to their offsprings.
According to Mendel, the unit of inheritance passed on from parents to offspring are genes. Hence Darwin's factors are Mendel's genes.
If Darwin knew of Mendel's work. It might have influenced his presentation of the idea of passing on favourable characteristics from parents to offspring in the light of genetics.
This would have made Darwin's work to have more empirical backing hence making it more widely accepted.

What do you think? Should human activity be documented on the geological scale why or why not if the human population were not the size it was today however it be different consider all force fears geosphere atmosphere hydrosphere and biosphere and the answer
Answer:
Environments on Earth are always changing, and living systems evolve within them. For most of their history, human beings did the same. But in the last two centuries, humans have become the planet’s dominant species, changing and often degrading Earth’s environments and living systems, including human cultures, in unprecedented ways. Contemporary worldviews that have severed ancient connections between people and the environments that shaped us – plus our consumption and population growth – deepened this degradation. Understanding, measuring, and managing today’s human environmental impacts – the most important consequence of which is the impoverishment of living systems – is humanity’s greatest challenge for the 21st century.
How did Mendel control which plants were
being pollinated?
A. He used artificial cross-pollination,
B. He only used female plants in his experiments,
C. He allowed any plant to be pollinated,
Answer:
Mendel was interested in the offspring of two different parent plants, so he had to prevent self-pollination. He removed the anthers from the flowers of some of the plants in his experiments. Then he pollinated them by hand with pollen from other parent plants of his choice.
Mendel controlled which plants were being pollinated by using artificial cross-pollination. Details about Mendel experiment can be found below.
How did Gregor Mendel control pollination?Gregor Mendel is referred to as the Father or Genetics because of his immense role in inheritance.

Carry out a tri-hybrid cross between XX(tall) YY(fat) ZZ(fair) and xx(short) yy(slim) zz(black). Find their genotypic and phenotypic ratios.
Answer:
Genotypic ratio = 100% XxYyZz
Phenotypic ratio = 100% tall, fat, fair.
Explanation:
For a trihybrid cross involving the genes XX which codes for tallness, YY which codes for fatness, and ZZ which codes for fairness with their alternate forms being xx, yy, and zz respectively; each gene will segregate into their respective alleles and combine to form gametes during meiosis, such that:
XXYYZZ ----> XYZ, XYZ, XYZ, XYZ, XYZ, XYZ, XYZ, XYZ
xxyyzz -----> xyz, xyz, xyz, xyz, xyz, xyz, xyz, xyz
These gametes then combine randomly during fertilization to give all XxYyZz offspring.
XYZ x xyz
XxYyZz
Since X is dominant over x, Y is dominant over y, and Z is dominant over z, then XxYyZz individuals that are produced from the cross would be tall, fat, and fair. Hence
Genotypic ratio = 100% XxYyZz
Phenotypic ratio = 100% tall, fat, fair.

Synaptic facilitation, a form of short-term plasticity, is primarily due to ______________. A. insertion of AMPA receptors into the post-synaptic membrane B. depletion of the releasable pool of vesicles C. prolonged elevation of presynaptic calcium levels following synaptic activity D. changes in Na channels located on the post-synaptic membrane
Answer:
The correct answer is - C. prolonged elevation of presynaptic calcium levels following synaptic activity.
Explanation:
Synaptic facilitation is a process of short-term plasticity that transiently increases synaptic transmission for less than a second, which is considered an essential part of playing a critical role in information transfer and neural processing.
It is evident that such an increase in the synaptic transmission is occur due to prolonged elevation of presynaptic calcium levels following synaptic activity.
